In order to achieve the purpose, the utility model adopts the following technical scheme: an output flange comprises a disk body part and a column body part which is integrally formed with the disk body part, wherein a shaft hole is axially arranged along the central area of the column body part, an internal spline is arranged inside the shaft hole, an external spline is arranged outside the cylinder part, a cavity is arranged on the disc part towards the first end face, the shaft hole is communicated with the cavity body, at least two first annular inner grooves are inwards and concavely arranged from the inner wall of the cavity body, the cylinder part comprises a first cylinder connected with the disc part, a second cylinder formed by extending outwards from the first cylinder and a third cylinder extending outwards from the second cylinder, the first cylinder is formed with annular location portion with disc body spare surface junction, first cylinder inside is formed with first ladder chamber, be equipped with two at least first annular ladder portions in the first ladder chamber.

Two first annular step portions are arranged in the first step cavity, and a second annular inner groove sunken to the inner wall of the first step cavity is formed between the two first annular step portions.

The second cylinder with first cylinder surface connection department is formed with annular positioning groove, the bottom surface of annular positioning groove is the arcwall face.

The second ladder chamber is formed in the second cylinder inner part, be equipped with two at least second annular ladder portions in the second ladder chamber.

The outer ring of the disk body part is provided with a plurality of first through holes penetrating through the upper surface and the lower surface of the disk body part.

At least two concave parts are inwards concave from the outer surface of the disc body part.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that: the design is more reasonable, simple structure and easy manufacturing, and easy installation and dismantlement moreover, in addition, internal spline can prevent circumferential direction, and structural strength is very high, and life is longer, can reduce use cost.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention is an output flange, including a disk body member 1 and a cylinder body member 2 integrally formed with the disk body member 1, wherein a shaft hole 21 is axially formed along a central region of the cylinder body member 2, an internal spline 22 fitted to an external spline of a spline shaft is formed inside the shaft hole 21, and an external spline 23 is formed outside the cylinder body member 2.

Referring to fig. 1 and 2, the disc member 1 has a cavity 12 facing the first end surface 11, and the shaft hole 21 is communicated with the cavity 12. At least two first annular inner grooves 121 are inwards recessed from the inner wall of the cavity 12. The outer ring 13 of the disc member 1 is provided with a number of first through holes 14 passing through its upper and lower surfaces. In addition, at least two recesses 15 are recessed inwardly from the outer surface of the body member 1 for mounting positioning. In this embodiment, the outer surface of the disc member 1 is recessed inward to form two concave portions 15, and the two concave portions 15 are symmetrically arranged.

Referring to fig. 2, the cylinder member 2 includes a first cylinder 24 connected to the disk member 1, a second cylinder 25 extending outwardly from the first cylinder 24, and a third cylinder 26 extending outwardly from the second cylinder, and an annular positioning portion 241 is formed at a connection portion of the first cylinder 24 and the outer surface of the disk member 1. The first cylinder 24 has a first step cavity 242 formed therein, and at least two first annular step parts 2421 are formed in the first step cavity 242, so that the inner diameter of the first step cavity 242 near one end of the cavity 12 is larger than that of the second cylinder 25 near the other end. In this embodiment, two first annular step parts 2421 are disposed in the first step cavity 242, and a second annular inner groove 2422 recessed toward the inner wall of the first step cavity 242 is disposed between the two first annular step parts 2421.

Referring to fig. 1, a ring-shaped positioning groove 251 is formed at the joint of the second column 25 and the outer surface of the first column 24, and the bottom surface of the ring-shaped positioning groove 251 is an arc-shaped surface.
